Different Researchs and Missions of Universe

The black hole absorbing light Firstly we need to know about black holes. Black hole are those holes which formed when two stars collapse each other when they live it’s complete life. Only black hole have capacity to absorb light completely without emitting any particle of light. They are small in size as compared to stars but having mass greater than star and also having higher density than a star. THE UNICORN : CLOSEST BLACK HOLE TO EARTH   Sir Tharindu Jayasinghe a doctoral student in astronomy at Ohio state found the closest black hole to the earth. It have nickname “ THE UNICORN ”.  The Unicorn is located about 1500 light years from Earth. This may be the smallest known black hole in ‘ The Milky Way Galaxy ’ and closest to our solar system. The mass of this black hole is 3 solar masses. This black hole is located right next to red giant star called V723 Mon in the constellation of Monoceros. Speed of Unicorn is approx. 1100,000 mph about 230 million light years from Earth. This is

Parker Solar Probe  Introduction:   As we need to know that the first ever mission had launched to study the sun at its nearest point that is solar corona (inner side of sun’s atmosphere ). The mission was launched on 12 August 2018 by delta IV heavy and on 3 October 2018 it fly by venus (moved by gravity assist of venus ) and it had taken the first perihelion round on 5 November 2018. Objective:  The objective of this mission is to unlock the different mysteries of the solar corona and Solar winds. It determined the structure and dynamics of plasma and magnetic field at the source of the solar wind and it also explored what mechanism used that accelerate and transport energetic particles. Dimensions and System used How it survive: It is able to survive at the extreme temperature due to a thermal shield that is made up of carbon composite materials that helped to make it unmeltable in extreme temperature ( approximately 20 - 25 lakh degrees fahrenheit ) at the solar corona. The cap i

DART Mission Space view DART stand for Double Asteroid Redirection Test. Firstly we need to know about what is dart mission ?what are the benefits from this mission ? and last what are the goals of this mission ? This mission is the first mission which demonstrating the method of asteroid deflection by changing motion of two asteroids in space by generating kinetic impact between them.  Mission is launched by NASA on 24th November 2021 from Vandenberg Space Force Based on a board of Space X Falcon 9 Rocket.  DART Mission works to deflecte the orbit of asteroids  DART will orbit the sun just outside the earth’s orbit for ten months there it is waiting for the Didymos (a asteroid system) is 780 m in diameter. It has a moonlet the Dimorphos 160 m in diameter. Which is the actual target of DART .  How DART Mission works  If it successfully change them moving direction or deflect the orbit of asteroid  then the mission is successful and it help in different way.  This first full mission i

Space view of Aurora Lights  Firstly, we need to know about the aurora. Auroras are the light which is produced naturally by collision of charge particles with gasses molecules present in the atmosphere. Predominantly sun in high latitude region like arctic and Antarctic. This light produces always at poles because magnetic field of earth is stronger on the poles and also the density of magnetic field lines is high there. Thus, a large number of charge particles found at the poles. The charge particles collide with the gasses to making them excited that cause  coloured visible light. When the charge particle collides with oxygen molecules then green light is emitted mostly but sometimes it produce red light and when collides with nitrogen molecules then more pink , orange or red colours emitted. Different types of Aurora Light seen on different places  These light appearing near the North Pole and South Pole. Scientist name these light as at North Pole light called “ Aurora borealis

JAMES WEBB SPACE TELESCOPE  JAMES WEBB SPACE TELESCOPE Firstly we need to know about the space telescope. It is a telescope which is placed in outer space and used to observe astronomical objects. And also used to study different types of light phenomenon like Aurora lights and to study hottest and most explosive object. Currently, NASA had launched a space telescope named as JAMES WEBB SPACE TELESCOPE [JWST] . It was made by international collaboration among NASA, the European Space Agency, and the Canadian Space Agency. It works as a replacement of Hubble Space Telescope. JWST was launched on 25 December 2021 on Arian Flight VA256. Firstly it was named as Next Generation Space Telescope and after some time name change to James Webb Space Telescope. There are some properties of JWST are Mass- 6161.4kg , Dimensions- 20.197m×14.162m , Power- 2KW. It operates in a Halo orbit, circling around a point in space known as the Sun-Earth Lagrange Point, approx 1500000km beyond Earth orbit aroun
